▎ 摘　　要

NOVELTY - The production method involves preparing a multi-layered graphene film (14) on a substrate. A dispersion liquid of metal nanowires is applied onto the multi-layered graphene film. A solvent is removed from the dispersion liquid to prepare a metal wiring on the multi-layered graphene film. A polymer solution is applied onto the multi-layered graphene film and the solvent is removed from the polymer solution to prepare a polymer layer. USE - Production method of stacked electrode used for photoelectric conversion device, such as a solar cell device. ADVANTAGE - The conductive polymer is used in the production method that functions as a leveling agent and provides conductivity for improving the device performance. The stacked electrode is produced without vacuum processes with a large area and a low cost. The metal wiring is bonded to the multi-layered graphene film easily, uniformly, and rigidly by spreading the metal nanowires directly on the multi-layered graphene film. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for producing a photoelectric conversion device. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic sectional view of the photoelectric conversion device with the stacked electrode.
